Great article. SEO as we know it is dying and it really will evolve into pure marketing. The technical aspects of SEO today is really just setting up your site to be crawled effeciently, making sure there are no errors or duplicate content, and building sitemaps to ensure everything is found as you want it. The rest is pure marketing, and targeting your content and getting links.

When I first got into SEO it was very technical and it was admittedly simple attempts at tricking the engine. This lives on in black hat SEO, but anyone serious about long term success with SEO is shaping and molding their content and brand. In the future people will be talking far less about SEO and more about marketing.
